How do you cut a 250 kg beam?

With a Robinson Band Saw, roller tables and elbow grease.

Sling brace being cut to the line.

Nearly there...

The curved sling brace was cut out of one piece of timber 5 m long x 500 mm wide x 200 mm thick.  It weighed 600 kg and to make it more manageable sections were cut away from the beam with the woodmizer saw mill to reduce the weight.  The pieces that were cut away were not wasted as we turned them into knee braces.
